With Namie, I don't think anything is typical. I really don't think she has a "typical" ballad or a "typical" dance song. Wild, In the spotlight, Alive, Black out, Want me want me, etc. They're all hot dance tracks that don't sound anything alike. It doesn't sound like she's reusing the same formula for further releases. Everyone is going to have a few songs that sound similar. Namie has Beautiful, Let me let you go, Contrail ~ballad version~, arigatou. Pretty much anything that's piano driven by Namie but they don't sound typical and they're few and far in between compared to Ayu's. Namie had a huge overhaul in her image, and music style back when it wasn't working. She started making relevant songs, and kept up with what's currently popular. Whereas Ayu is releasing generic winter ballad #17.

I agree.
Namie's voice is nice and fits dance and ballad songs a lot.
Ayu's voice is so annoying sometimes, she sounds like a big idol girl sometimes.

In my opinion.
